Why it’s on today’s list

What we checked

We opened this offer on Butter LONDON’s own site at 11:10 AM ET on November 2, 2026 and recorded the price shown there. The figure above is the price we saw, not a price reported by a feed.

Butter LONDON lists $24 as the regular price, which makes $12 a 50% cut against the retailer’s own comparison. We quote that comparison as the retailer publishes it; we have not independently confirmed the item sold at $24 for any sustained period.

Butter LONDON has not announced an end date for this offer, so we do not print one. We re-check it every morning and remove it at the next check once it stops working.
